NEW GENERATION SUPRA TIG 400(1)

Supra TIG 400 ( I ), a new generation inverter based pulsed TIG machine is very handy and compact for easy operation. Even at very   low current values, the arc is well controlled andstable thus  nabling excellent weld quality. The adjustable current up-slope and  down - slope are distinct features of this machine.

SALIENT FEATURES

• The special design of the machine helps in making it quakeproof, moisture-proof and dust-proof.
• The machine is designed for high duty cycles.
• The high frequency arc strike, helps in achieving sound, radiographic quality welds.
• Pulse welding function.
• Time controlled spot welding.
• Dual operation modes, i.e. 4T / 2T.
• The machine can be used for MMAW and TIG processes.

This Welding Power Source Supra SAW 1000 is a multi-function power source with constant-voltage and constant current characteristics. In addition to  ubmerged welding, it can also be used as a welding power  source for stick welding, carbon arc air gouging, electro-slag  welding and high diameter wire GMAW/FCAW. The users can also  select its functions optionally. The power source has adopted  controllable Silicon Controlled Rectifier. Based on adjusting  ccuracy  and fine dynamic characteristics, it can automatically  balance fluctuations in voltage of input power rapidly. This ensures  that the arc is stable, enabling the user to achieve high quality  welding easily. 

SALIENT FEATURES

• Due to digital display, the operator finds it easy to view current and voltage.
• An auto power-off switch gets activated, when the machine is not in use for
• more than 30 minutes, thus in turn saving power cost.
• The machine can run on two-speed mode - variable and constant.
• PWM is used for adjusting the speed (wire feed and welding tractor travel), so that the speed is not affected by the input voltage and environmental temperature.
• The power source can be used for multiple functions: SAW, MMAW, Carbon arc gouging, GMAW, FCAW and Electro-slag welding.
• Very reliable weld quality.
